DEFICIENCY Condition Re orted As required by Criterion V of Appendix B to 10CFR50, and as implemented by Carolina Power and Light PSAR, Section 1.8.5.5, "Activities affecting quality shall be accomplished in accordance with procedures.
Procedures applicable to control of welding electrodes used in construction of the containment liner are included in Chicago Bridge and Iron's 'Contract Quality Assurance
- Handbook, Contract 84031/2, Div. 4'.
Section 8 of this document requires all welding material at the jobsite to be stored in locked storage areas or locked electrode ovens."
Contr ar y to the above, on October 15,
- 1979, a welding electrode return oven was found unlocked and unattended.
Corrective Ste s Taken and Results Achieved:
The described deficiency occurred during the process of repairing the return oven.
The return oven was tripping a circuit breaker which was traced to a faulty male electr ical plug.
The storage attendent and workmen left to obtain tools and repair parts leaving the rod oven door open with 8 to 10 electrodes in it.
These electrodes were later disposed to preclude any of their use.
Corrective Ste s Taken to Avoid Further Noncompliance CB&I has given their personnel the following specific instructions to assure that when repairing electrode ovens in the future, they are not deficient in following their storage procedures:
"One of the following precautions must be taken when repairing electrode ovens:
(1) Oven door remains locked at all times.
(2)
Remove all electrodes from oven and place in another locked storage ar'ea.
(3) Assign storage attendent to be present during repair time while door remains unlocked."
Date Hhen Full Com liance Mill be Achieved Full compliance is considered to have been accomplished through modification to steps taken by CB8X in the event repair is required to an electrode oven in the field.
As investigated and found by CB&X, none of the affected electrodes were used.
